Εφαρμογή:
Used in the main distribution boards, for use primarily on mains power distribution systems to protect connected facility from transient overvoltage.
Suitable for the low voltage main power distribution cabinet/box of buildings, and the facility connected between single phase AC power supply and system in parallel.
Use of attention:
1. The grounding path should be as short as possible, and the length should not exceed 1.5 meters.
2. When installing, pay attention to cables coming in and out of surge protective devices, so as to avoid the two coupling of surge.
3. The protected equipment must have good grounding, and the grounding impedance is in accordance with the relevant national standards.
4. After correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
